Steps to Calculate GCD of 33, 27, 21, 43 using LCM Formula
Given numbers are 33, 27, 21, 43
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(33, 27) = 297
GCD(33, 27) = ( 33 x 27 ) / 297
= 33 / 27
= 33
Step2:
LCM(3, 21) = 21
GCD(3, 21) = ( 3 x 21 ) / 21
= 3 / 21
= 3
Step3:
LCM(3, 43) = 129
GCD(3, 43) = ( 3 x 43 ) / 129
= 3 / 43
= 3
So, Greatest Common Divisor of 33, 27, 21, 43 is 1
